What Is Oracle Fusion Middleware
 Oracle Fusion Middleware is a collection of
standards-based software products that spans a range
of tools and services: from Java EE and developer tools,
to integration services, business intelligence, and
collaboration.
 Oracle Fusion Middleware offers complete support
for development, deployment, and management of
applications.

What is SOA
 SOA stands for Service Oriented Architecture.
 SOA is an architecture for building business
applications.
 SOA provides an enterprise architecture that
supports building connected enterprise applications

SOA Diagram

Benefits of SOA
 Loose coupling
 Reusability
 Interoperability
 Scalability
 Flexibility

Benefits of SOA Continued…
 Set of integrated capabilities:
 Messaging
 Service discovery
 Orchestration
 Web services management and security
 Business rules
 Events framework

SOA Standards Continued…
 The standards SOA leverages are:
o Service Component Architecture (SCA) assembly model
 Provides the service details and their interdependencies to
form composite applications.
 SCA enables you to represent business logic as reusable
service components.
o Service Data Objects (SDO)
 Specifies a standard data method

 XSL Transformations (XSLT)
o Processes XML documents and transforms document data
from one XML schema to another.
 Java Connector Architecture (JCA)
o Provides a Java technology solution to the problem of
connectivity between the many application servers in
Enterprise Information Systems (EIS).
 Java Messaging Service (JMS)
o Provides a messaging standard that allows application
components based on the Java 2 Platform, Enterprise Edition
(Java EE) to access business logic distributed among
heterogeneous systems.

 Web Services Description Language (WSDL) file
o Provides the entry points into a SOA composite
application. The WSDL file provides a standard
contract language and is central for understanding
the capabilities of a service.
 Simple Object Access Protocol (SOAP)
o Provides the default network protocol for message
delivery.

 MDS
o It stands for Meta Data Service
o It is a central repository inside OFMW
o Two types : File Based and DB based
 DVM
o It stands for Domain Value Maps
o Used at runtime to operate on actual data values

 BPEL
o BPEL stands for Business Process Execution Language
o BPEL processes provide process orchestration and
storage of a synchronous or an asynchronous process.
 Mediator
o It routes events (messages) between different
components
 Business rule
o It enables you to design a business decision based on
rules.

SOA Service Components Continued…
 Human task
o It provides workflow modeling that describes the tasks
for users or groups to perform as part of an end-to-
end business process flow.
 Spring Context
o It enables you to integrate Java interfaces into SOA
composite applications

 BPEL
o What is BPEL
o Interaction Patterns
o BPEL Activities.
o Partner link

BPEL Continued…
 Using BPEL, you design a business process that
integrates a series of discrete services into an end-
to-end process flow.

BPEL Continued…
 Activities
o Receive
o Pick
o Assign
o Switch or If

BPEL Continued…
 Activities Continued..
o While loop
o Invoke
o Throw
o Scope
o Reply

BPEL Continued…
 Interaction Patterns
o One Way Messages
 Only request will be sent. It doesn’t expect any response.
o Synchronous
 It waits for response of each request.
o Asynchronous
 It sends a request and response can come later.
o Define Service Later

BPEL Continued…
Interaction Patterns Continued…

BPEL Continued…
 Partner link
o It is a link or reference to other SOA service
components
o It defines a relationship between two services.

SOA Installation

SOA Installation
 Jd eveloper
 Web logic Server
 RCU

SOA Installation Continued….
 Memory and Disk Space Requirements
o At least 1GHz CPU
o 5.15 GB of disk space to install
o Minimum 3 GB of RAM for smooth running of SOA
suite

deployment, Connection Factory
 How to create JMS server, Persistence Store, JMS Module,
Sub deployment, Connection Factory

 How to create a JMS Topic in Web logic server

JMS Adapter Continued…
 Consuming a message from JMS Queue using BPEL
 Consuming a message from JMS Topic using BPEL
 Producing a message to JMS Queue using BPEL
 Producing a message to JMS Topic using BPEL
 Where and how to see the produced message in Weblogic
server

Web Service
 What is Web Service Adapter
 How to configure a Web Service Adapter using JDeveloper
